Seeking to force a 10 digit number, any ideas of references?

Hi all,

This is my first ever post on Genii. I have written up a presentation that now needs a method. I am seeking input on forcing a 10 digit number from an audience of 30+ people. I recall someone putting a gaffed calculator on the market years ago, but I have no current information on this.

If anyone has any ideas of references to put me in the right direction of study, that would be great. Again, for the presentation I have in mind, I am seeking to randomly have an audience help me arrive at a 10 digit number of my choosing.

Thank you in advance for any assistance you may lend.

borrow a $1 bill, switch it for one with a known s/n as you pass it to another spec to read it off. And if bills don't have 10-digits, who's to say yours couldn't?

That day's winning lotto numbers?

Ten digits is an AWFULLY large number to try to force, but if you must, DrDanny's suggestion is probably your best bet. However since the serial numbers on US currency consist of only 8 digits, but are preceded and succeeded by different letters of the alphabet you would have to convert those letters to numbers in order to have ten digits; i.e., A-I = 1-9 respectively, for the other letters (J-Z) convert them to a single digit as follows: M=13, 1+3=4, so M=; Z=26, 2+6=8, so Z=8, etc.

Just curious, why a 10 digit number?

My guess is that it is for a phone number...

Marc DeSouza discusses a wonderful method using an ungimmicked calculator on his Master Works of Conjuring Vol 2 DVD. I believe it was originally published in The Jinx, which Marc credits.

Jack,
Below is a link for the Marc DeSouza DVDs.

Mark credits Bob King's marketed item from the 80's called "Calculation Sensation". He also states that Bob King claimed it wasn't original with him, he was the first use it in a magical application.

In my above post, I stated that it might be in Jinx. That was incorrect.

DeSouza's calculator force (or a version of it) just happens to be in the Sept Genii which just arrived here at the Fortress of Solitude.

Whether or not it is, Barrie Richardson's phone book test from "Theater of the Mind" could be adapted to force a 10 digit number if the phone book is from an area in which various area codes are overlaid in the same geographical area, like Los Angeles.

A very simple way would be to force a series or sequence of spot cards. I used to do this for a book test using jumbo cards (with six or seven digits) and, combined with a convincing false shuffle, it was very effective.

Jeff, thanks for the clarification.

I did not want to not credit and contact Mark, when I re-issue some of my o.o.p. work later this year.

Thanks again for clearing things up,

Jim
